Silicon Labs, known as the "core technology" company and listed on NASDAQ under the ticker SLAB, has expanded its energy-efficient industrial-grade microcontroller (MCU) EFM32® Gecko family to deliver enhanced performance, more features, and lower power consumption. The newly launched EFM32GG11 Giant Gecko MCU family offers the most advanced feature set in the low-power MCU market, ideal for applications like smart metering, asset tracking, industrial and building automation, wearables, and personal healthcare. These MCUs provide up to 72MHz processing speed, large memory capacity, a wide range of peripherals, hardware accelerators, and complete software tools—including the industry-leading Micrium® OS.
As IoT applications grow increasingly complex, requiring multi-sensor integration, advanced user interfaces, and sophisticated algorithms, the need for energy-efficient MCUs has never been greater. The Giant Gecko MCUs are designed to meet these demands by offering higher integration, improved performance, and optimized power efficiency.
Tom Pannell, senior director of marketing for Silicon Labs IoT products, said: “Giant Gecko MCUs bring a high-performance user experience that was once only possible with high-power MCUs. Based on years of development, the Giant Gecko family offers developers a significant leap in performance, functionality, and design capabilities.â€
Key features of the Giant Gecko family include:
- An ARM® Cortex®-M4 processor core for performance-intensive applications.
- The largest on-chip memory available in a single MCU (up to 2MB flash and 512KB RAM), supporting larger code sizes, debugging, OTA updates, data logging, and rich graphical interfaces.
- SD/MMC and Octal/Quad-SPI memory interfaces for expanded storage options in data-heavy applications.
- Fast wake-up/sleep transitions and a low-power architecture enable autonomous sensor access and support for low-power peripherals.
- Ultra-low power consumption: 77µA/MHz in active mode and 1.6µA in deep sleep mode.
The Giant Gecko MCUs also integrate a comprehensive communication interface, including 10/100 Ethernet MAC for IP-based industrial control, a Wi-Fi module via SDIO for cloud connectivity, dual CAN bus controllers for industrial applications, a crystal-less USB controller for cost-effective and ultra-low-power USB, and advanced LCD drivers with alpha blending and ultra-low-power segment LCD support.
Additionally, the family includes a capacitive sensing engine that simplifies touch application development with low-power wake-up capabilities. Security is also a key focus, with an energy-efficient security accelerator, a Security Management Unit (SMU), and a NIST-certified True Random Number Generator (TRNG) for robust encryption and secure randomization.
Available in QFN, QFP, and BGA packages, the Giant Gecko MCUs support up to 192 pins and are pin-compatible with existing EFM32 MCUs. They are fully compatible with the entire EFM32 MCU and EFR32 Wireless Gecko SoC family, enabling extensive software reuse and reducing development time and costs.
Silicon Labs’ Simplicity Studio development tools support the Gecko MCUs, providing a unified Eclipse-based environment for one-click project setup. It includes graphical configuration, energy monitoring, network analysis, and capacitive touch tools, along with software examples and documentation. The Giant Gecko MCUs natively support Micrium OS, and developers can easily access Micrium tools through Simplicity Studio.
The EFM32GG11 Giant Gecko MCU engineering samples became available in early 2018, starting at $5.66 for 10,000 units. A development kit, the SLSTK3701A Giant Gecko, is also available at a suggested retail price of $99.99. For orders, visit the official website.
Dual Band Router Module
Dual-band WiFi module refers to the WiFi module that supports both 2.4GHZ and 5GHz bands. The dual-band WiFi module can operate in the 5Ghz band, which is much cleaner and can easily avoid interfering with each other. The advantage of 2.4G is that it has good ability to penetrate the wall, and the disadvantage is that it is easy to be disturbed. The advantages of 5G are strong anti-interference ability, wide band width, high throughput rate, and strong scalability, but the disadvantage is that 5G is only suitable for indoor small-range coverage and outdoor bridge, and the attenuation effect of various obstacles on it is much larger than 2.4g.
Dual-band WiFi module has a stronger and more stable Wifi wireless signal, higher transmission speed, and can make wireless devices more power-saving, to meet the future high-definition and big data wireless transmission needs.
When selecting a dual-frequency WiFi module, we should pay attention to these parameters of the WiFi module: size, package, frequency range, data rate, transmission rate, transmission distance, communication interface, power supply voltage, antenna interface, etc.
Dual frequency WiFi module can well meet the functional needs of users, increase the competitiveness of the product, while the WiFi module is easy to use, can shorten the user product development cycle, speed up the product market! Users can make choices according to actual needs!
Choosing a dual-band WiFi module may need to pay attention to the following points:
(1) Consider the transmission power of the dual-frequency WiFi module
The transmitting power of the WIFI module is generally about 18dBm, and the transmitting power of the high-power WIFI module is about 28dBm.
(2) Transmission rate
Consider whether the dual-band WiFi module supports MIMO technology (that is, allows multiple antennas to send and receive multiple spatial streams simultaneously)
(3) Consider the application interface that dual-band WiFi modules can provide, which is also very important.
(4) According to the requirements of the application scenario to choose the dual-band WiFi module, not the higher the configuration, the better, the application is good, excess waste!
